hiACl-HNE FOR CRUSl-HNG AND STEMfv'HNG TOBACCG=LEAV S.

SEEGIFIGATILZ? forming part of Letters Patent No. 321,61, dated July 7, 13:23.

Application filed August U. 1854. (No model.) Patented in England Jammy 3, 1884, No. 530.

following to be a full, clear, and exact de scription of the same, reference being bad to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a side elevation of my improved machine; Fig. 2, a side elevation of a part of the machine, viewed from the opposite side; Fig. 3, a front elevation, and Fig. etatop plan view. The remaining figures are details.

Fig. l is asection of adjacent parts of one of zo the wheels and its brush, showing the construction of the parts enlarged. Fig. 1 is a detail elevation of the clearing-disk; Fig. 2,

an enlarged section of adjacent parts of the cutterwhecl and its companion or female;

Fig. 3, an enlarged section of the movable knife,whieh is operated by a rod through the hollow standard, and Fig. 5 an enlarged section of the knife-wheel and its shaft.

Referring to the drawings, M designates an 0 ordinary cast-iron frame properly braced,

and it furnishes journal-bearings for the several shafts 1, 2, and 3, which, by a train of gearing, I, are connected and forced to revolve together. The shaft 1 carries a wheel, A,

having a concave periphery and a central recess, a, into which recess operates a dislrcutter, (2, of a cutting and crushing wh eel,B, which will be described. This wheel 13 is hung rigidly upon the shaft 2, and is formed of three disks securely clamped together and to the shaft 2, the inner disk,d,having a cuttingedgc, and the two outer disks, Z, having rounded peripheries which correspond with the surfaces upon either side of the peripheral 5 groove in the wheel A, against which they abut when the machine is in operation.

Upon the shaft 3 is hung, rigidly, a clearer, J. This clearer is composed of a central metal disk, J, having teeth which operate to keep the groove (L clear, and two outer disks, j, being provided with bristles ",or the like, adapt ed to sweep the rounded surfaces upon either side of the groove a in the wheel A.

Grooved wheels, male and female, fora similar purpose have been before known, and I attach importance to these constructions in their relations to each other. The groove a gives a freedom to the action of the knife (Z, allowing it to dividethe stem of the tobaccoleaf, and the peculiar brush J keeps the wheel A clear of sap gum, or portions of the leaf. The rounded portions of the wheels A B serve to crush the stem, so as to leave the leaf in a inerchantable condition for use. It is not only desirable to cut off the butt of the stem of each leaf, but, in case of some of the stems being too woody, also to entirely strip the stem. I provide convenient means for such results.

E designates a hollow standard secured to the main frame, in which is fixed astationary grooved jaw, 72, as shown. Reciprocating in guides above this jaw h is a cutter-jaw, g, which is connected by a vertical rod, g, having a heart-cam, b, with an eccentric-pin, f, hung upon a disk, f. as shown. This disk or pulley f is connected with the shaft- 2 by a belt, 0. The leaf, having been treated between the wheels A B, is taken by the operator and placed upon the jaw h. The jaw or knife is forced down,and not only cuts off the butt of the stern, which is allowed to waste, but the beveled surfaces upon either side of the cutter serve to grip the leaf long enough to allow the operator to strip the leaf from the stem if he so desires. To provide for this period of rest between the jaws g h,1 equip the rod g with the heart-shaped rain 6 mentioned, the operation of which in its relation to the eccentric-pin f will be readily understood.

Power is applied to the machine through the pulley 0 upon the shaft 2, a loose pulley, G,be ing provided to stop the machine at will.

I) designates an inclined feed-table, which reaches up to the junction between the wheels A and B.

What I claim as new is-- 1. In a machine, substantially as described,

the combination, with the shafts 1, 2, and 3, geared together, and the wheel A, having peripheral groove a and rounded portions upon eithersidethereoflofthc cutter-wheel B,having cutting-disk d and disks 1, with rounded peripheries, and the clearer J, having toothed central disk, 7', and bristles, as and for the purposes set forth.

2. The hollow standard E, having jaw h, and the eccentric-pin f, combined with the rod 9, having heart-cam b, the reciprocating knife and connections with the powershaft, the parts hghaving clamping-shoulders adapt ed to detain the leaf after the stem has been cut, as set forth.
